To all whom it may concern Be it known that I, ALFRED M. CHAFFEE, a citizen of the United States, residing at Oxford, in the county of Worcester and State of Massachnsetts,'have invented certa in new and useful Improvements in Means for Delivering Moistened or Glue-Coated Paper and Similar Fabrics, of which the following is a specification.

My present invention relates to an improvement in mechanism adapted for facilitating the manipulation and delivery, from a continuous web as desired, of a covering paper or fabric in moist, glue-coated, hu-

midified, or more or less damp, pliable, weak, or flimsy condition; a prime object being to provide a simple and eflicient means for the automatic feeding or delivery of moist glue-coated paper or similar fabric, in broad webs, and controlled for starting the feed by giving a slight pull or draft upon the end of the paper itself, as required, and for stopping the feed-delivery by merely relinquishing the pull or hold upon the paper; thereby relieving the attendant from the exertion and labor that might otherwise be necessary for advancing the moistened gluecoated fabric, and also relieving the moistened and weakened paper from excessive strain and from liability of becoming wrinliled or torn as it is brought forward over the covering table or place of use.

. organization of means for the moistening or humidifying of a web of paper as it passes to said feeding or delivering means, and for regulating the humidifying action, as more fully hereinafter explained.

Another object is to provide a roller feed delivery device pivotall fnlcrumed for rocking action, and a ctional driving means therefor that is put into and out of action by shifting the position of the rockable members upon their fulcrum axes.

Also, to afford a construction of the roller supporting means that will permit ready reirlegse and re-assembling of the individual ro I attain these objects by a mechanism, the nature and operation of which is illustrated in the drawings, wherein H Figure 1 represents a part side part 'sectional elevation of mechanism embodying myinvention. Fig. [2 represents a front bling or covering table to which the fabric or moist glue-coated paper is delivered for recelvlng such members as are to be inclosed ,therein, and C indicates a cutting-oil shear for severing. sheets from the end of the web of paper.

My improved feed-delivery mechanism comprises a pair or plurality of rolls 2 and 3 arranged parallel with each other and made of suflicient length to extend across the Web of paper 4, which may be of any required width, more orless. Said rolls are disposed adjacent to each other, but preferably not in contact, and are mounted in a limitedl oscillatable frame or carrier, composed 0 end housings or bearing-members 5 that are supported upon the mam frame, or brackets fixed thereon by pivots 7 or fulcrum joints located at position eccentric to and preferably at a short distance rearward and in line with each other, so that the carrier or housings 5, together with the rolls mounted therein, can have a limited upward and backward swinging movement upon said fulcrum pivots. The rolls 2 and 3 may he journaled 1n hearings in the housings, or may be supported therein in a manner for ready detachment ."and re-assembling, as hereinafter more fully described. The housings at the opposite ends are rigidly connected together by rods or cross-bars 6. j

The rolls are intergeared or connected to rotate in unison, by intermeshing spur-gears 8 upon their axles or equivalent means arranged within or adjacent to one of the housings.v The under roll 2 is provided with a frictional faced Wheel 9 fixed on its axle, and a counter-matching friction-whcel 10 is mounted upon a stud or arbor suitably supported upon the frame. The latter friction wheel is provided with a pulley 12 for a driving belt 13, whereby said frictional wheel ,10 is operated. The friction-wheels 9 and 10 are located in such relation that the frictional surfaces contact when the carrier or housings and rolls are oscillated forward or depressed, (see Fig. 3) but are relieved or out of contact when said carrier and rolls are oscillated backward in a slight de ee. (See Fig. 4.) A stop device 14 is provided for limiting the backward swing and suitable adjusting means is provided for regulating the amount of clearance space be; tween the friction surfaces when retracted.

A spring 15 or equivalent means is provided for affording a backward pull or pre-' ponderance for swinging the carrier or housing frame to its rearward position of oscillation for throwing the friction wheels 9 and 10 normally out of contact.

Fig. 5 shows the construction of the roll mounting devices when it is desired that the rolls be readily removable and replaceable to facilitate cleaning. The rolls are made of thin metal tubes with heads, one of the heads is fitted with a socket 16 or means for interlockingly engaging with the axle on which the gears 8 are fixed, while the other head of the roll is provided with a hollow bushing 17, and a screw stud 18 is threaded through the housing 5 and has a cylindrical end that is inserted within said bushing, and upon which the roll turns. A check-nut 19 is arranged upon the stud to screw up against the side of the housing for retaining the adjustment.

By turning back the screw stud its end is withdrawn from the bushing and the roll can then be taken out of the carrier, its opposite end being freed by a mere endwise movement. It can as readily be replaced by a reversal of this operation.

20 indicates an upright inclosed box or chamber wherein the paper acquires moisture, and from which the web passes beneath the guide roll 21 to the delivery roll 2. In the lower part of said chamber there is an oblong open-topped trough or pan 22 having a steam-pipe therein, and adapted for containing water which is heated and evaporated by the steam pipes, making a rising vapor for moistening the paper as it passes through the chamber. Above the pan 22 is a carrier-roll 23 mounted in bearings 24 which are preferablyadjustable up and down on their supports for varying the amount of paper surface exposed to the vapor at one time, and thus regulating the degree of dampness imparted to the paper.

25 indicates means for applying glue to one surface of the paper, comprising a gluereservoir provided with a delivering roll 26 over which the paper is passed, and having suitable guide bars for directing the web in contact with the glue-delivering roll.

44 indicates the roll of paper or fabric from which the web 4 is supplied. Said roll of paper may be supported by any suitable means at a convenient location. The apparatus may be constructed to accommodate a web of paper or fabric of any desired width; ordinarily widths of from two to four feet, more or less, are employed. .The web 4, as herein illustrated, passes from the roll 44, over the glue-roll 26 and beneath the guideroll and up to and over the carrier-roll 23 within the moistening chamber 20, where it becomes humidified and rendered inore or less soft and weakened; thence under the guide 21 to the primary feed-delivering roll 2, thence upward at the front of said roll and rearward beneath and forward over the delivering-roll 3 to the cutting-off shear C or place of use B.

In the operation of my improved feeddelivery mechanism, the attendant reaches across the shear line and takes hold of the end of the moist paper near the corners, and gently pulls it toward the front. This slight pull swingsforward the carrier and feed-roll mechanism upon the housing fulcrum pivots 7, causing the friction-wheel 9 to come into engaging contact with the power driven friction-wheel 10, thereby immediately imparting forwardly rotative movement to the rolls 2 and 3, which then automatically reel off the web 4 in a uniformly smooth, regular, and easy manner so long as the attendant carries forward the free outer end of it; thus requiring only such action by the attendant as will keep the delivered portion of the paper taut to a degree suflicient t0 counterbalance or maintain the preponderance of the oscillating carrier or roll-housing frame at forward position; the driving power doing all the work of pulling the web from the roll 44, passing it over the glue-roll 26, through the damping process, and about the several intermediate rolls or guides. When the end of the paper has reached the predetermined mark or position above the table the attendant merely stops the forward movement of his hands, and the automatic delivery of the web immediately ceases, by reason of the normal backward swing of the housing frame and feed-rolls taking the friction members 9 and 10 out of contact as the preponderant force exerts itself at the rearward side of the fulcrum axis. When the paper is delivered over the table to the required length, the attendant brings the shear G into action and severs the sheet from the web, leaving the newly severed end of the web in condition for repeating the operation. The shear is operated by the rod 28, lever 30, and cam 31 on shaft 32; the

pulley 33 being combined with the camshaft by an automatic stop clutch 34 that is let into action by connections having a controller (latent 35 located to be moved by the hand of the operator as the web is drawn to the desired limit.
